Hi, there is a friend of mine who just planned on getting a tattoo made and she wants to know what the tips for tattoo aftercare are? What all has to be done; she is getting a big tattoo. She wanted to know if the bigger the tattoo does it mean the more care. She saw someone get out of a tattoo parlor and his hand was wrapped in cellophane paper, could you explain to us why that had been done. What are the creams to be applied on the tattoo?
